Abstract
A control system for controlling air pressure to a tire during the testing cycle of a tire uniformity machine includes a mechanical regulator connected to a source of air and a transducer disposed adjacent the tire and in communication with a central processing unit and the regulator to match sensed variations with predetermined testing pressure programmed into the central processing unit and activate the regulator as required.
Claims3
In a tire uniformity machine in which tires are inflated by air pressure for bead seating on opposed chucks for testing purposes, a control system comprising:
- a) a source of air under pressure in fluid communication with the tire;
- b) a servo-controlled mechanical regulator;
- c) at least one transducer positioned adjacent the chucks;
- d) said regulator being connected to said source of air and said at least one transducer;
- e) said at least one transducer being set to read chuck closing pressure and signal said regulator;
- and
- f) said regulator providing testing pressure to the tire upon receiving a chuck closing pressure signal from said at least one transducer.
A method of controlling tire inflation pressure in a tire uniformity machine in which a tire is seated between opposed chucks and tested under pressure, comprising the steps of:
- a) presetting a servo-controlled mechanical regulator to a desired testing pressure;
- b) providing a transducer adjacent the chucks;
- c) reading the chuck closing pressure by the transducer and signalling the regulator;
- and
- d) applying the preset testing pressure to the tire by controlling air from the main air supply source.
